No Gulf production, LOOP, refining, or LNG terminals are in play; the only tracked system is far east near Cabo Verde with low formation odds. Watch for any westward track extension or chance increase before this becomes Gulf-relevant.

NHC outlook text (verbatim)
For the North Atlantic...Caribbean Sea and the Gulf of America:
Eastern Tropical Atlantic: An elongated area of low pressure centered a few hundred miles southwest of the Cabo Verde Islands is producing a large but disorganized area of showers and thunderstorms, extending from these islands southwestward into the eastern Tropical Atlantic. Environmental conditions appear only marginally conducive for some development of this system over the next day or two before upper-level winds become too strong for any further development by midweek. Regardless, heavy rainfall is expected over the next few days for portions of the Cabo Verde Islands as the system moves slowly northward to north-northwestward.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 7 days...low...20 percent.
